Aggregate Data from multiple sources and “Slice and Dice By Context”
Enables efficient information access and timely collaboration between departments and agencies, regardless of location.
Enables analysts to build complex data models by applying a variety of contexts to a given set of data, providing a multi-dimensional view of information.
Provides robust security features to regulate access to sensitive data and apply existing authentication policy.
Policy-Based Access
